Slide 9

9 Unique in Education Performance Curve Fact #1: Education do not guarantee its products. No of Students Performance Distribution :

Slide 10

10 No of Students Performance Distribution -- Traditional -- eLearning Fact #2: Effectiveness of traditional face- to-face learning and eLearning is about the same.

Slide 11

11 Effectiveness the mature model -more students doing better (peak- to-peak) -better mean student performance -higher performance -lower failure rates No of Students Performance Distribution

Slide 12

12 If we can reverse engineer the outcome, what can we do? No of Students Performance Distribution Starting with the end in mind, what can we do to achieve this desired outcome?

Slide 13

You have taught them; Have they learnt? Thomas C. Reeves Professor Emeritus of Learning, Design, and Technology University of Georgia

Slide 14

Quality from Different Perspectives Quality of content Usually not the issue Standard textbooks, derivative material, multimedia courseware Quality of teaching process You have taught them; have they learnt? Quality of the (self- directed) learning process Impact on Student performance, Institutional reputation Student value-add quality 14

Consider: Is Lecture Recording a)an IT project, or b)a media project c)a network project

Slide 23

Key ideas and considerations Economical way to create/maintain content Authoring/creation/capture software solution on low-cost PCs Fast availability and quick post-processing Robust, reliable and resilience Highly scalable platform Content distribution Network Campus license for wide distribution

Slide 24

2 Modes of Lecture Recording 1.Live recording in the Lecture Theatre Control Room School Clubs provided manpower (paid on hourly rate) and we provided support in training, logistics and software customisation 2.Professors DIY Self-recording in office using web camera and headset

Teaching Paradigm Traditional Approach Teacher teach Students listen and learn Assignments are given Assignments are submitted for marking Students read their marked assignments Participative Model Teacher teach Students listen and learn Assignments are given Students participates online (content co- creation) Students read their own and other peer contributions

Slide 64

Show me another example

Slide 65

Example: Experimental Aerodynamics Background: Professor interested in developing a package to help students better understand wind and water tunnels in exploring aerodynamics Limitation: wind and water tunnel facility cannot accommodate class of 140 enrolled students Solution: professor create documentary-style video to induct students to wind and water tunnels

Multiple varied answers to the same question Good, poor, incomplete, right, wrong, partial, model answers

Slide 71

So? What does all this mean?

Slide 72

Findings: Quality of Learning View video course content segmentation + interactive learning activities + group participation More engagement as more senses are used More active participation More thought More reflections More self-directed learning More peer-peer collaborative learning and assessment and latent feedback Develops more discerning learners Professors have a better gauge of students learning

Slide 73

Findings: Outcomes of Learning Activities Use of LAMS open-ended questions Responses read by class-mates enhances students learning Students learn from each other - peer learning and peer assessment Students compare their responses with other students awareness of different responses to same question Student develops (higher order thinking skills) judgment on response quality Know & Share (Content Co-creation) Know & Share (Content Co-creation) Compare Learn & Connect Judgment & Discernment Judgment & Discernment
